Several previous changes conspired to make a mess of the thread list
in static binaries. This was most obvious when trying to call
pthread_key_delete(3) on the main thread.

Add getsid() system call to bionic for
all architectures. This is needed for various tools
(e.g. perf).
Adding the getsid system call was done in 3 steps:
() add getsid system call (function name and syscall
number) to libc/SYSCALLS.TXT
() generate all necessary headers by calling
libc/tools/gensyscalls.py. This patch is adding
the generated files since the build system
does not call gensyscalls.py.
() add the system call signature to libc/include/unistd.h

Expecting the memory in a forked child process to be sane wrt threading
is a bad idea. An example of a problem is when the parent process has
the malloc lock and a child process is forked. The malloc lock in the
child will appear locked by a thread that doesn't exist.
This change aims to make bionic more compatible with glibc by reseting
the malloc lock in the child forked process, as well as holding it
during the fork. This is a feature in dlmalloc 2.8.6 called
LOCK_AT_FORK. In general this feature isn't necessary as a forked
process will then exec. Some bad applications rely on being able to use
features like malloc before the exec and having multiple threads running
in the parent program. This isn't a problem with glibc and this patch
makes it not a problem for bionic.
Unfortunately for use in bionic, LOCK_AT_FORK has an issue as internally
it uses pthread_atfork that in bionic uses malloc. This leads to the
LOCK_AT_FORK initialization deadlocking with pthread_atfork's call to
malloc due to the malloc lock. This change moves the pthread_atfork logic
in LOCK_AT_FORK to be called without the malloc lock held.

Clang and _FORTIFY_SOURCE are just plain incompatible with
each other. First of all, clang doesn't understand the
__attribute__((gnu_inline)) header. Second of all,
Clang doesn't have support for __builtin_va_arg_pack()
and __builtin_va_arg_pack_len() (see
http://clang.llvm.org/docs/UsersManual.html#c_unimpl_gcc)
Until we can resolve these issues, don't even try using
_FORTIFY_SOURCE under clang.

Legacy ARM shared libraries use this generic version of atexit(),
which queues exit functions for invocation at program exit, at
which time the library may have been dlclose()'d, causing the
program to crash.

To properly support legacy ARM shared libraries, libc.so needs
to export the symbols __dso_handle and atexit, even though
these are now supplied by the crt startup code.
This patch reshuffles the existing CRT_LEGACY_WORKAROUND
conditionally compiled code slightly so it works as the
original author likely intended.

Added a missing call to _resolv_cache_query_failed for another fail

Add a GNU_STACK marker to crtend* files. This tells the linker
that these files do not require an executable stack.
When linking, a missing GNU_STACK marker in any .o file can prevent
the compiler from automatically marking the final executable as NX
safe (executable stack not required). In Android, we normally work
around this by adding -Wa,--noexecstack / -Wl,-z,noexecstack.
For files like crtend.S / crtend_so.S, which are included in every
executable / shared library, it's better to add the GNU_STACK note
directly to the assembly file. This allows the compiler to
automatically mark the final executable as NX safe without any
special command line options.

Also make the errors more readable, since none of us seemed to know
what they actually meant. The new style is still as verbose as the
old, but that's probably necessary in the absence of chained exceptions
in C. Here's what you'd see if you try to boot after removing
libsurfaceflinger.so:
32267 32267 E AndroidRuntime: java.lang.UnsatisfiedLinkError: Cannot load library: (linker.c:1629, pid 32259) soinfo_link_image: could not load library "libsystem_server.so" needed by "libandroid_servers.so"; caused by (linker.c:1629, pid 32259) soinfo_link_image: could not load library "libsurfaceflinger.so" needed by "libsystem_server.so"; caused by (linker.c:709, pid 32259) load_library: library "libsurfaceflinger.so" not found

RETRY macro may retry command if result is -1. In this
case the command was "connect < 0" instead of just
connect. The comparison will not return -1 and thus
retry is never done. This is now corrected so that
interrupts will cause retry instead of fail.
(There was no other negative side effect of the bug.
The result code from RETRY was used in an if-statement
and it would be true for all negative connect results.
This was according to expectations.)
